[Observium] Alert Checker question

Hi, Adam,

is it possible to create an Alert Checker which will check number of trunks (see picture - trunk1,3,6 = 3) for trunk6 ? Something like: if it greater than 1, alert me? Trunk1,3,6 are discovered by Observium itself, I do not know how to check that type of item.

Thanks in advance,

Miro
